Default 1:8 OFNA GTP 2 Steering Problem ...

I recently purchase a new RTR from OFNA which was my first of that kind. I've been in the hobby for some years, but anyhow long story short I'm having some issues. The servo included with the car is a joke it isn't even capable of turning the wheels from left to right. I have a new 1700mah 6V battery which I fully charged but it still doesn't help. I've was told eariler I should upgrade but what doesn't make sense to me is why OFNA would choose a servo combination insufficent to the needs of the car ...

Well to start off, let me say, welcome to the
RC Tech forums Twisted_Metal. Yea, I have never
seen a RTR made by any company that came with
desent servos. I think they do that because most
of the radios that come with the RTR's don't have
any way to adjust the servo throw end points.
I like to run the Hitec 5955 or 7955 servo for the
steering. Any servo with over 200in./oz. of torque
should do. You may want to replace the t/b servo
also. They are known for stripping gears and causing
unwanted runaways. Take a look in the "For Sale"
threads on this site, someone is always selling hi
quality servos for a good price.

That will do just fine. Be carefull of the rtr t/b
servo. I have seen a few overheat real fast and
when they do they go from the neutral position
to the wide open position and lock there. I had
it happen on an Ofna Picco buggy not long ago
and it came close to costing me a $300 engine.
I knew not to take a chance on the rtr servos
but I figured that they would be ok for a quick
test drive,WRONG!!! I ran over an eigth of a mile
trying to catch up with that damned buggy.
